Temperature sensors play an important role in daily life, from managing climate control in the home to maintaining safety in industrial settings. One specific example of a temperature sensor with analog and digital output is the TMP35GT9. This device is versatile enough to be used in both commercial and scientific applications.

The TMP35GT9 uses a thermistor to provide linear output over an extended temperature range. It is a three-terminal device, with an output voltage that is exponentially related to absolute temperature. The thermistor is connected to two voltage supply pins: a power supply voltage (Vdd) and a ground (GND). An analog output voltage is generated between these two pins as the temperature changes. This output voltage is inversely proportional to the temperature, meaning it decreases as the temperature increases. The slope of this line (sensitivity) can be adjusted with a single external resistor.

In addition to providing analog output, the TMP35GT9 also has a digital open-drain output. This output is open-drain, meaning it is a type of transistor voltage switch that can be used to turn on and off outputs at specific temperatures. The hysteresis of this output can also be adjusted with an external resistor, making it possible to set temperature thresholds for alarms and other functions.

The TMP35GT9 is a versatile device that can be used in a variety of applications. It is particularly well-suited for use in climate control systems, such as HVAC systems, or in operating industrial machinery, such as boilers and turbines. It is also suitable for use in scientific applications, such as monitoring environmental conditions in laboratories.

The TMP35GT9 is a reliable and versatile temperature sensor that can be used in many commercial and scientific applications. It features an analog output for measuring temperature in addition to a digital open-drain output that can be used for alarms or other functions. Its adjustable sensitivity and hysteresis make it suitable for a variety of applications, from climate control to industrial machinery.
